So you're saying it's probably not a coincidence that the pipe junction that failed
the other night is for one of the water lines (the cold one) to my washing machine ?
Interesting. Makes sense I guess. The inertia of water flowing in a pipe is analogous
to an electrical inductor, in which voltage (water pressure) is proportional to derivative
of current (water flow). So an abrupt change in flow generates a big pressure pulse.

Time to get one of these water-hammer arrestor dohickies. Why are they better than
one you just improvise with a vertical dead-end piece of pipe with air in it ?
